It depends on what you are going to play. The campaign seemed to get horrible reviews but I haven't played it yet. Multiplayer on the other hand is wonderful.
I'm a huge call of duty fan and I personally think that halo 5 multiplayer is very similar to cod but just doesn't have all the annoying things people hate about cod.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
